* mod_cgid and suexec have a problem co-existing. suexec sees a null
command string sometimes.
* There is a bug in how we sort some hooks, at least the pre-config
hook. The first time we call the hooks, they are in the correct
order, but the second time, we don't sort them correctly. Currently,
back when this is fixed. rbb
* Root all file systems with <Directory /> for
WIN32/OS2/NW permissions
Status: patch brought forward from 1.3.14
WIN32 and OS2 need review [William Rowe, Brian Harvard]
* Win32: Get Apache working on Windows 95/98. The following work
(at least) needs to be done:
- winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
specific code that is still not in NT only code paths
- IOL binds to APR sendfile, implemented with TransmitFile, which
is not available on 95/98.
- Document warning that OSR2 is required (for Crypt functions, in
* Win32: Test access logging with multiple threads. Will the
native file I/O calls serialize automagically like the
CRT calls or do we need to add region locking each time
* Win32: Complete the revamp the service environment and relocation
into the WinNT MPM. Changes ServerRoot service registry
parameter into ConfigArgs for multiple service startup parameters.
signals are not being acknowledged. Close window and shutdown
OtherBill is working on this and will finish over the weekend.
* We need a thread-safe resolver, at least on Unix.
Status: The best known candidate would be something from
Status: Greg asks, "why? doesn't gethostbyname_r() handle this?"
* The AddInputFilter and AddOutputFilter directives do not allow the
administrator to remove or reorder filters. Once a filter is added
in a container, it is present in any subcontainers. It can only be
added to the filter chain after any filters specified in enclosing
* remove the --disable-shared from the subdir config of APR(UTIL)
before the final release. (in fact, it might even be nice to
Note: we need to do a "make install" for APR(UTIL) so the shared
libraries can be installed properly. We could also use that
point to install include files (rather than have Apache
know everything that needs to be installed from the
sub-packages). The original impetus for doing the
disable-shared was because the shared lib wasn't getting
installed and a "make clean" in aprutil would make Apache
* users who want to install third-party modules into the Apache
source tree (for static linking) need to have autoconf and
libtool installed. This is because the module needs to have its
config.m4 incorporated into ./configure, which means "buildconf"
Note: This is in part because we have removed the "extra" directory.
In the Apache-2.0 repository, this directory had a
config.m4 file that allowed people to add external modules by
specifying --with-module on the configure line.
* ap_vrprintf() needs to handle more than 4K
* mod_dir should normally redirect ALL directory requests which do
not include a trailing slash on the URI. However, if a "notes"
flag is set (say, via BrowserMatch), this behavior will be
disabled for non-GET requests.

* Usability: Sanitize the MPM config directives. MaxClients in
the threaded MPM is totally misleading now as it has little to
do with limiting the number of clients (it limits the number
of child processes). Bill proposed nomenclature change to
something like "StartWorkers, MaxWorkers, etc." that could
apply to most all the MPMs (with some notable exceptions).
Bill would be happy with changing MaxClients to MaxServers
to make it agree with the operation of the StartServers
* Doug M. reports that there is a there is a problem with both
threaded and prefork mpms children not properly handling
SIGTERM which results in the server taking a long time to
Status: Paul Reder is investigating...
* A design problem with the scoreboard can cause the threaded
MPM to get in a state where it will no longer serve requests.
When MaxRequestsPerChild is hit, a threaded process will begin
allowing it's idle worker threads to exit. The child process
may have one (or a few) threads serving really long responses
over slow client connections, which will prevent the child
process from exiting. The problem is that the
perform_idle_server_maintenance code will NOT start a new
process to replace the dying child process until the dying child
has exited because the new child needs to use the old childs
space in the scoreboard. The scoreboard and
perform_idle_server_maintenance need to be redesigned.
Status: Several proposals discussed on new-httpd (April 16, 2001)
RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
* Performance: Get SINGLE_LISTENER_UNSERIALIZED_ACCEPT
optimization working again. Bill would like to see this
working for the threaded MPM, then prefork.
* mod_tls is very specific to OpenSSL. Make the API calls
more generic to support other encryption libraries.
* Performance & Debug: Eliminate most (and perhaps all) of the
light weight memory management functions that allow freeing
memory (putting it back into a memory pool) when it is no
longer needed. Enabling simple debugging features like guard
bands, double free detection, etc. would be cool but certainly
* Eliminate unnecessary creation of pipes in mod_cgid
* the autoconf setup should be fixed to default to using the
in a layout should be overridable on the command line. Plus,
what we do right now just doesn't seem to fully fit into how autoconf
works, eg. AC_PREFIX_DEFAULT issues.

* mod_status ExtendedStatus SS (seconds since last request) is
bogus because of an uninitialized field in the scoreboard.
Status: Cliff is working on this
will allow us to error out if a threaded MPM is chosen on a
platform that doesn't support threads.
* Combine log_child and piped_log_spawn. Clean up
http_log.c. * Document mod_file_cache.
* OS/2: Make mod_status work for spmt_os2 MPM.
* Win32: Win9x console window still won't play nice with the
close window, logoff and shutdown scenarios.
Status: OtherBill will move the patch forward from 1.3.15, once we
get our other Win9x issues solved.
* Win32: Add a simple hold console open patch (wait for close or
the ESC key, with a nice message) if the server died a bad
death (non-zero exit code) in console mode.
Status: OtherBill is bringing forward same ugly hack from 1.3.13
* Platforms that do not support fork (primarily Win32 and AS/400)
Architect start-up code that avoids initializing all the modules
in the parent process on platforms that do not support fork.
would eliminate some code in the Win32 branch that essentially
duplicates what is in APR.
* There are still a number of places in the code where we are
losing error status (
i.e. throwing away the error returned by a
system call and replacing it with a generic error code)
* Win32: Implement reliable piped logs on Windows
* Mass vhosting version of suEXEC.
the dbmmanage employs the first-matched dbm format. This is not
necessarily the library that Apache was built with. Aught to
rewrite dbmmanage upon installation to bin/ with the proper library
* use apu_dbm in mod_auth_dbm
Status: Greg +1 (low-priority volunteer)
Some additional items remaining:
- case_preserved_filename stuff
(use the new canonical name stuff?)
- find a new home for ap_text(_header)
- is it possible to remove the DAV: namespace stuff from util_xml?
* ap_core_translate() and its use by mod_mmap_static and mod_file_cache
are a bit wonky. The function should probably be exposed as a utility
function (such as ap_translate_url2fs() or ap_validate_fs_url() or
something). Another approach would be a new hook phase after
"translate" which would allow the module to munge what the
translation has decided to do.
Status: Greg +1 (volunteers), Ryan +1
* Explore use of a post-config hook for the code in
http_main.c which
calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
ap_sort_hooks() [to reduce the logic in main()]
* read the config tree just once, and process N times (as necessary)
* (possibly) use UUIDs in mod_unique_id
and/or mod_usertrack
* (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
into a VirtualHost container) to 2.0.
* the LTFLAGS = -export-dynamic in the
config.m4 is wrong. it is getting
added multiple times during the config process. The -export-dynamic
building Apache modules).
* APR-ize resolver stuff in mod_unique_id (Jeff volunteers)
* callers of ap_run_create_request() should check the return value
for failure (Doug volunteers)

needed. Apache 1.3 just never stashed "multipart" into
r->content_type. We should probably follow suit since the
byterange stuff doesn't want the rest of the code to see the
multipart content-type; the other code should still think it is
dealing with the <orig_ct> stuff.
Status: Greg volunteers to investigate (esp. since he was most
likely the one to break it :-)
Other features that need writing:
* Finish infrastructure in core for async MPMs
